Simplistic but fun. I like the concept and look of it.
The kill plane for the donuts is a bit high. I would try to swing down to catch a donut only to have it disappear before hitting the bottom of the stage. It's a small gripe but a bit jarring.
Yeah it's my fault for not adjusting the code I was using. When I get back to it I'm definitely tightening up little things like that.
